Question for the OP why are there commands for busy box? Can't an installation of busy box occur once you've rooted your phone and installed Titanium? I'm just thinking that if there is a way to take additional code out of there that might be it.
I think my fear is there is no back up that is done like with SPRecovery. And can you overclock this puppy if I did root?
The fact that you do it all on your phone makes it interesting. I may consider it.
